Brandenburg-Ansbach issued 2/3 Thaler pieces in the 1670s as part of a broader North German adoption of the Gulden-Thaler convention, which pegged the 2/3 Thaler to 2/3 of the Reichsthaler — effectively creating a coin worth 16 Groschen that could circulate alongside both imperial and regional currency systems. John Frederick, who ruled Ansbach from 1667 until his death in 1686, was among the more financially active of the Hohenzollern cadet line, minting extensively to fund his court and manage obligations to the Franconian Circle.
